The DBH 8339 radial shaft seal is a lip seal that stops lubricant from escaping and blocks dust, water or particles from entering at the point where a shaft rotates inside a housing. It is press-fitted into the housing and runs on the shaft surface, with a flexible lip that compensates for minor misalignment and vibration. It is a wear part: when oil leakage or dirt ingress appears, it is replaced.

This item is a seal from the DBH line, identified by part number 8339. Its dimensions are 100 mm shaft diameter (d), 162 mm housing diameter (D) and a height of 13.00/17.50 mm (h), with design A 157. That double height indicates a profile with a stepped section: the lip and the body do not have the same development, which is common when the seal combines sealing with axial retention or covers a housing with a recess. Design A 157 defines the geometry of the lip and the metal body.

Typical applications for a seal of this size are in transmission and process equipment with large-diameter shafts: gearboxes, centrifugal pumps, mixers, mills, screw conveyors and machine tools. It also appears in rollers and wheel hubs of road or agricultural equipment, where grease or oil must be contained and mud or water kept out. In all cases it works alongside a bearing or bushing that shares the same shaft and housing.

To select it, check that the shaft diameter and the housing diameter match the part being replaced and that the height is compatible with the housing depth and the available space. Check the condition of the shaft surface: if it has a groove or wear, the new lip will not seal properly and you should consider a repair sleeve or a seal with an offset lip. During installation, lubricate the lip, avoid striking it and apply force on the outer ring, never on the lip.

If part number 8339 is not available or you need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part and the housing. With that data we look for the equivalent in DBH or another brand in the same family, respecting the lip design and the elastomer type. If the shaft is worn, we can also evaluate sealing alternatives.
